Question

. Host A and B are communicating over a TCP connection, and Host B has already received
from A all bytes up through byte 126. Suppose Host A then sends two segments to Host B
back-to-back. The first and second segments contain 80 and 40 bytes of data, respectively. In
the first segment, the sequence number is 127, the source port number is 302, and the
destination port number is 80. Host B sends an acknowledgment whenever it receives a
segment from Host A.
a. In the second segment sent from Host A to B, what are the sequence number,
source port number, and destination port number? (1 mark)
b. If the first segment arrives before the second segment, in the acknowledgment of
the first arriving segment, what are the acknowledgment number, the source port
number, and the destination port number? (1 mark)
c. If the second segment arrives before the first segment, in the acknowledgment of
the first arriving segment, what is the acknowledgment number?
